The arrangement is mold sections and ,molten 'metal plunger such that uponv return movement of ,the in diferent positions of adjustment from plunger to original position, the coil springs those shown 1n' Figure 2. l 18"separate the mold sections and 6 and 90 Figure 4 is an end view. A rthe coil springs-17 move the inner die block 1 is a pot containing the molten metal \holder 7 and the female nozzle 8 away from, and 2 isa malenozzle, for the'pa'ssage of' the male nozzle 2.l Y 40; molten metal mounted -upon the' pot and With the'rOnStructiOnJas thus 'far ffie-y communicating with the ump'or forcing. scribed it will be seen `that by' permitting 95 the molten inetal'in Jprefllitermined amounts fluid, such as water, under pressure to, enterA through the nozzle.. 4 is a'sectional mold the base. end of the cylinder 13, the plunger which as shown com rise'sthe inner and 14.- will be moved outwardly to lmove the outer die blooks' an 6 respectively. lwhich die block holders 1O-andJ-7 horizontally tocooperate to form the mold 'cavity'.Y 7 is ward the male nozzle 2, compressing the coil 100 theholder for the-'inner `diefblockjhavinfgg' springs 18 r and 17 and bringing the `d1e the female nozzle 8 mounted thereon for-*block sjand 5 into engagement with each cooperating' withthe' male nozzle 2, and other-and the 4female. nozzle 8 into engagealso the; passa eway Q therethrough for' ment ,with'the male nozzle.

The puinp 3 for forcing the molten metal into the mold, comprises the cylinder 19 secured to the bottom of the pot 1 and located beneathV the molten metal and also comprises the plunger 2O slidably engaging in the cylinder. The inner end of the cylinder communicates with the male nozzle 2 by means of the upwardly extending passageway 21. 22 is a transversely extending aperture in the outer end of the plunger and 23 is a roch arm extending downwardly into the molten metal and having the rounded end 2li engageable in the aperture 22, the arrangement being such that upon rocking of the reclr arm from the position shown in Figure 2, to the position shown in Fi ure 3, the plunger will be moved outward y and in its outer position, permits of the entrance of the molten metal into the cylinder 19 and passageway 21 through the` opening 25 between the .inner end of the plunger and the outer end of the cylinder. This opening is preferably formed by cuttin away a portion of the inner end of the p unger. 26 is a rock shaft above the pot l and is actuated by means of the rock arm 27 pivotally connected` to the rod 28 of the plunger 29, which latter is reciprocable, within the cylinder 30. To permit of swinging the rock arm 27 through its arc, the cylinder 30 is pivotally mounted upon its support 31 as at 32. Fluid under pressure is also alternatively admitted into the opposite ends of`this cylinder for actuating Athe plunger in opposite directions.
